STRUCT DPNI_ATTR(9)

💅 struct dpni_attr 💅

okay bestie, welcome to the Kernel API Manual page for struct dpni_attr — the whole vibe is DPNI attributes, and it’s giving main character energy. 🦋

✨ NAME ✨

struct dpni_attr — the structure representing DPNI attributes. periodt. 💖

✨ SYNOPSIS ✨

here’s the exact shape, bestie, no cap:

       struct dpni_attr {
           u32 options;
           u8 num_queues;
           u8 num_tcs;
           u8 mac_filter_entries;
           u8 vlan_filter_entries;
           u8 qos_entries;
           u16 fs_entries;
           u8 qos_key_size;
           u8 fs_key_size;
           u16 wriop_version;
        };

🎀 Members 🎀

• options — any combination of these options, bestie: DPNI_OPT_TX_FRM_RELEASE, DPNI_OPT_NO_MAC_FILTER, DPNI_OPT_HAS_POLICING, DPNI_OPT_SHARED_CONGESTION, DPNI_OPT_HAS_KEY_MASKING, DPNI_OPT_NO_FS. 🫶
• num_queues — number of Tx and Rx queues used for traffic distribution. 💫
• num_tcs — number of traffic classes (TCs), reserved for the DPNI. 🎀
• mac_filter_entries — number of entries in the MAC address filtering table. 💅
• vlan_filter_entries — number of entries in the VLAN address filtering table. 🌸
• qos_entries — number of entries in the QoS classification table. ✨
• fs_entries — number of entries in the flow steering table. 🦋
• qos_key_size — size, in bytes, of the QoS look-up key. defining a key larger than this when adding QoS entries will result in an error. 😭
• fs_key_size — size, in bytes, of the flow steering look-up key. defining a key larger than this when composing the hash + FS key will result in an error. 💀
• wriop_version — version of WRIOP HW block. the 3 version values are stored on 6, 5, 5 bits respectively. 👑
